NeoVis is an application that allows one to visualize in real-time the contents of an EOgmaNeo hierarchy. It uses sockets to communicate with the client program. It can be connected and disconnected seamlessly, provided the client code contains the appropriate visualization update function.
The following commands can be used to build the NeoVis library:
mkdir build; cd build
cmake command can be passed a
CMAKE_INSTALL_PREFIX to determine where to install the visualization executable.
On Windows it is recommended to use
cmake-gui to define which generator to use and specify optional build parameters.
Version 3.1, and upwards, of CMake is the required version to use when building the library.
Make sure to compile EOgmaNeo with the optional SFML dependency, as this will enable the ability to use the visualizer.
Example usage from EOgmaNeo Python bindings (C++ and other bindings are similar):
# Initialize and construct an EOgmaNeo hierarchy, for example h = eogmaneo.Hierarchy() h.create([ ( chunkSize, chunkSize) ], [ chunkSize ], [ True ], lds, 123) # Initialize the VisAdapter v = eogmaneo.VisAdapter() v.create(h, 54000) # EOgmaNeo Hierarchy, port # ... # In simulation loop: v.update()
Once NeoVis is started, use the
Connection button and
Connection Wizard dialog box to open a connection to your hierarchy. Simply specify the address (localhost, if on same machine) of the client, and make sure that both applications are using the same port (default 54000). Once
Connect! button has been pressed, and the status switches to "Connected", you should see several windows appear.
Each layer has a window for its hidden layer SDR (Sparse Distributed Representation). If you right-click on a particular unit in the SDR (highlighted in green), additional windows containing the weight matrices going in and out of that unit will appear.
At the moment, SDR and weight matrix visualization are the only features of NeoVis. Despite this, we found it quite handy for debugging our programs. If your application isn't functioning properly, it may be a good idea to pear into the network with NeoVis!
Please note that the visualizer only works with simulation-like environments. It assumes that the client is running in real-time, and it streams whatever the latest state is for visualization. This makes is particularly handy for visualizing the EOgmaNeo hierarchy during reinforcement-learning-like tasks and other realtime applications.
